Matt 8:16 – When the Heaven was come, they brought unto Him many that were possessed with devils : and He cast out the spirits with His word, and healed all that were sick:

Jesus healed the sick and delivered the oppressed through His word. You can get healed and delivered through the word of God. Since Jesus did not use any other means, like candle or bathing in the river. The only things you need are the word of God and Faith in His word.
